I recently began having issues where the randomly our smartermail page will not load but will sit at a loading screen as shown in the image I have included below. We have not always had this issue so I didn't believe it to be an IIS issue as we have made no changes to IIS since install. That being said I am not sure if this is an IIS issue or a smartermail issue and am not sure where to look for clues as to the cause. If I refresh the page it loads immediately. I am currently running smartermail 12.2.5283
